    Help with Postfix + Dovecot on Fedora 20


    Hi guys.

    Please cut me a little slack. I'm a career IT professional having worked in many towers (Network, Storage, PHP scripting, Winblows server admin, AD, a little MySQL, telecom, blaa blaa). But, I've always dabbled in UNIX - never been a professional admin or whatever. Just kind of fought my way through personal projects (mostly hosting) using Web resources over the years. I've managed to accomplish everything I sought out to do except for my current task - MAIL SERVER.

    So, I have this Fedora 20 VM I've used for virtual Apache hosting for several years with no problem. I've run MySQL as the backend for some forums and a couple of other Web sites. I'm now setting up an ecommerce store using OpenCart. So far, so good. The store is working fine.

    In attempting to get email hosting up and running, and avoid paying Google apps (since they now charge), I installed Postfix as the MTA and Dovecot for local delivery. I read through a ton of documentation and thought I did everything right. I have the proper A/CNAME and MX records setup. I even created an SPF record to make the taskmasters at GMAIL happy and accept my test messages for something other than spam. I created what I thought was the proper pinholes in IPTABLES (25, 143, 465, 587, 996). I edited virtusertable accordingly. Added the mail server to /etc/hosts, and made all the other changes I thought would be required to work.

    Issues: I can send email out using Pine with no problem. Gmail even states the sender is authentic via SPF validation. I can't send mail back - lost into oblivion. Netstat reveals that I am indeed listening properly. I can connect to ports 25, 143, and 143 locally but NOT from outside. I'd be glad to post the output of postconf, snippets of maillog or any other diagnostic info that might help.

    Any assistance you all can provide would be GREATLY appreciated.

    -Freddy

    BTW, I can connect to port 143 from outside but not the others. And I meant to write port 993 above, not 996. Also, my ultimate goal is to enable SMTP server intercommunication obviously and only some version of secure IMAP (TLS or SSL).

    Last but not least, test messages are not bouncing but actually getting queued somewhere. I just don't know where unfortunately. They're not in the expected /var/spool/mail or /var/mail.
    Checking Webmin (don't hate me), I see them:

    Code:
    Freddy	2014/10/28 21:57	1.76 kB	test 2
    Freddy	2014/10/28 16:20	2.49 kB	Re: Test IMAP 10-28

    Your postfix server doesn't seem to start properly. Try stopping it and then restarting it. From the error, it looks like /var/lib/postfix/master.lock is the culprit. Your postfix server doesn't seem to start properly. Try stopping it and then restarting it. From the error, it looks like /var/lib/postfix/master.lock is the culprit. Check this out: Postfix master dead but pid file exists

    After that, try telnetting port 25 from localhost, local network and external/public ip.

    Try these:

    In the server itself:
    Code:
    telnet localhost 25
    In other systems in the same network as the server:
    Code:
    telnet <ip address of your postfix server> 25
    In other systems located in different public IP:
    Code:
    telnet <public ip address of postfix server> 25
    and
    telnet <domain of your mail server> 25
